Buying tickets for any games depends on a lottery which is already taking registrations. Early games may be a little bit more accessible, played in several other cities as well as Paris, but if you luck out and get a ticket it may not be in the city you prefer. The Euro cup has developed the nice tradition of fans gathering in public squares to watch the later games on big public TV screens, maybe as close as the casual fan can get to the action. Studies have shown that these big public spectacles, such as the World Cup final or the Olympics, scare off more tourists than are attracted, so that hotel occupancy in the last week may fall below normal. The prices won't drop, though -- that's the best bet of all.
